Accurate, economical and high-throughput gene and genome synthesis is essential to the development of synthetic biology and biotechnology. New large-scale gene synthesis methods harnessing the power of DNA microchips have recently been demonstrated. Yet, the technology is still compromised by a high occurrence of errors in the synthesized products. These errors still require substantial effort ...
Introd u ction Clinical chemistry, for decades restricted to a limited number of chemical tests, has, in recent years, through an increasing awareness of the value of the laboratory investigation of disease, and the introduc tion of automation and sophisticated instru mentation, expanded its field of operations to include a bewildering variety of tests. Advances in biochemical knowledge have ...
A vibrio-bacteriophage system isolated from San Francisco Bay mud is described. The vibrio lyses readily in distilled water and appears to be a new species. In contact with the phage it becomes lysogenic and forms large clumps. The phage presents no unique features.
We have been successful in generating several lines of transgenic mice and pigs that contain the human beta-d-mannoside beta-1,4-N-acetylglucosaminyltransferase III (GnT-III) gene. The overexpression of the GnT-III gene in mice and pigs reduced their antigenicity to human natural antibodies, especially the Galalpha1-3Galbeta1-4GlcNAc-R, as evidenced by immunohistochemical analysis. Endothelial ...
Enzymatic-detergent decellularization treatments may use a combination of chemical reagents to reduce vascular tissue to sterilized scaffolds, which may be seeded with endothelial cells and implanted with a low risk of rejection. However, these chemicals may alter the mechanical properties of the native tissue and contribute to graft compliance mismatch. Uniaxial tensile data obtained from nati...
Lysostaphin is a potent enzymatic anti-staphylococcal agent that lyses the cell walls of staphylococci in vitro. Studies described in the preceding paper demonstrated that lysostaphin rapidly killed staphylococci, was unaffected by human serum, and maintained its activity after prolonged incubation at body temperature.' Unlike the penicillins, lysostaphin was active in vitro against very large ...
a new method for the synthesis of water soluble polyaniline (pani) using hemin chloride (h.c) in the presence of hydrogen peroxide (h.p) is presented. hemin chloride is an effective catalyst for the oxidative polymerization of aniline in the presence of hydrogen peroxide at room temperature. the uv- vis absorption spectra of the product show a distinct absorption peak at 430 nm in ph 4.0 b...
